What action should be taken if a speed recorder is found to be malfunctioning during a Daily Inspection?

Reporting the malfunction of a speed recorder during a Daily Inspection is the appropriate action to take because speed recorders are critical for ensuring safe operations. These devices help monitor and control the train's speed, which is essential for maintaining safe travel limits and preventing accidents. By reporting the malfunction, the train crew ensures that trained personnel can evaluate the situation and provide guidance on how to proceed, which might include placing the locomotive out of service until the issue is resolved. This approach prioritizes safety and compliance with regulations rather than taking any unilateral actions that could compromise operational integrity or safety.
